building from the middle pom of a (parent,child,grandchild) heirarchy fails
---------------------------------------------------------------------------
Key: MNG-2619
URL: http://jira.codehaus.org/browse/MNG-2619
Project: Maven 2
Issue Type: Bug
Components: POM
Affects Versions: 2.0.4, 2.0.5, 2.1
Reporter: Richard van der Hoff
Attachments: maven-project-middlepom.patch
Given a heirerchy of projects - parent, child, grandchild - with <parent> and
<module> links between them in the normal way:
Attempting to start a build from the middle of the heirarchy - ie, the "child"
- causes maven to attempt to download the parent from the repository - even if
the version in the filesystem is correct in terms of {artifact,group,version}.
The problem appears to be that the ProjectBuilder first reads the child pom,
and caches the result (but not the parent pom). The reactor then makes the
ProjectBuilder read the grandchild pom, and hence the child pom (which now
comes from the cache), and the parent pom (which it can't find).
This is much easier demonstrated than explained :/
The attached patch fixes the problem by making sure that all the projects in
the heirarchy (including the parent) are added to the cache. It also includes a
test case to demonstrate the problem.
